I tend to agree with this principle in general, but in the other hand here, we want to be able to share XPath expressions between products. Those that understand this extension will use it, but the other ones have to be able to execute the expression anyway (providing that on those products the bindings are set in another way). But I agree that this could silent some errors, and that is bad. > >But it feels a bit like an abuse. > It depends what the semantics of the extension function. > If they are defined as adding namespaces to the static > context, then I think this would be a violation of the > XPATH language, because the static context is no longer > static (its contents changes during evaluation of the > language). But the adding of the bindings can be done while compiling the expression, before evaluating it, isn't it?
